--- Comment #6 from imitrichev <imitrichev at muctr dot ru> ---
I think, while patching one should consider also warn on `for` loop empty body.
Whilst we can write something like
int i=0;
for (; i<5; a[i]=10, i++);
it is assumed to be not a great programming style.
int main()
{
for (; 1<2; );
if (1==1);
while (1==1);
return 0;
}
Now it warns only on `if` loop:
g++ empty.cpp -Wempty-body -o empty.out
empty.cpp: In function "int main()":
empty.cpp:4:10: warning: suggest braces around empty body in an «if» statement
[-Wempty-body]
It is really would be helpful to detect infinite loops caused by odd ';' after
`for` and `while` without debugger.
